Оценить диагностическую эффективность эхокардиографии с физической нагрузкой у пациентов с подозрением на ишемическую болезнь сердца (ИБС), а также изучить ее прогностическую значимость в отношении среднесрочного прогноза.Материалы и методы. В ретроспективное исследование были включены 643 пациента в возрасте 45-76 лет (средний возраст 58,4±9,7 лет) с подозрением на ИБС, но без типичных симптомов стенокардии. Всем пациентам была проведена эхокардиография с нагрузочной пробой на беговой дорожке с использованием модифицированного протокола Брюса. Движение стенки левого желудочка оценивалось с помощью 17-сегментной шкалы, при этом коронарная ангиография или коронарная компьютерная томографическая ангиография (ККТА) использовались в качестве эталонного метода для оценки диагностической эффективности. Медиана времени наблюдения составила 36,2 месяца. Первичной конечной точкой было крупное неблагоприятное сердечно-сосудистое событие (MACE), включающее сердечную смерть, нефатальный инфаркт миокарда, плановую реваскуляризацию на основании объективных признаков ишемии миокарда и госпитализацию по поводу нестабильной стенокардии. Для оценки диагностической эффективности использовался анализ ROC-кривой, для анализа выживаемости — метод Каплана-Мейера, а для анализа факторов риска возникновения MACE — модель регрессии пропорциональных рисков Кокса.Результаты. Из 643 пациентов у 253 (39,3%) была диагностирована обструктивная ИБС (стеноз ≥70%), а у 246 (38,3%) - были положительные результаты эхокардиографии с физической нагрузкой. Чувствительность эхокардиографии с физической нагрузкой для диагностики обструктивной ИБС составила 76,3%, специфичность — 88,5%, площадь под ROC-кривой (AUC) — 0,824, диагностическая точность — 83,5%. В течение периода наблюдения было зарегистрировано 89 случаев (13,8%) MACE. Трехлетняя выживаемость без серьезных сердечно-сосудистых событий (MACE) составила 72,8% в группе с положительным результатом стресс-эхокардиографии и 94,2% - в группе с отрицательным результатом (p&lt;0,001). Многофакторный регрессионный анализ Кокса показал, что положительный результат стресс-эхокардиографии, индекс оценки подвижности стенок, концентрация N-концевого фрагмента предшественника мозгового натрийуретического пептида и возраст являются независимыми факторами риска MACE (все p&lt;0,01).Заключение. Стресс-эхокардиография продемонстрировала хорошую диагностическую точность у пациентов с подозрением на ИБС, не имеющих типичных симптомов стенокардии. Кроме этого, выявлена ее прогностическая значимость в отношении неблагоприятных сердечно-сосудистых событий в среднесрочной перспективе. Стресс-эхокардиография может использоваться для стратификации риска и принятия клинических решений в этой популяции.</p></abstract><trans-abstract xml:lang="en"><p>Objective    To evaluate the diagnostic efficacy of exercise stress echocardiography in patients with suspected coronary artery disease (CAD) without typical angina symptoms, and to explore its predictive value for intermediate-term prognosis.Material and methods    A total of 643 patients aged 45–76 yrs (mean age 58.4±9.7 yrs) with suspected CAD but without typical angina symptoms were retrospectively enrolled in this study. All patients underwent treadmill exercise stress echocardiography using the modified Bruce protocol. Left ventricular wall motion was assessed using the 17 segment scoring method, with coronary angiography or coronary computed tomography angiography (CCTA) as the reference standard for evaluating diagnostic efficacy. The median follow-up time was 36.2 mos. The primary endpoint was a major adverse cardiovascular event (MACE) including cardiac death, non-fatal myocardial infarction, elective revascularization based on objective evidence of myocardial ischemia, and hospitalization for unstable angina. ROC curve analysis was used to evaluate diagnostic efficacy, the Kaplan-Meier method for survival analysis, and a Cox proportional hazards regression model to analyze risk factors for occurrence of MACE.Results    Of the 643 patients, 253 (39.3 %) were diagnosed with severe obstructive CAD (stenosis ≥70 %), and 246 (38.3 %) had positive results of exercise stress echocardiography. The sensitivity of exercise stress echocardiography for diagnosing severe obstructive CAD was 76.3 %, specificity was 88.5 %, AUC was 0.824, and diagnostic accuracy was 83.5 %. During follow-up, there were 89 cases (13.8 %) of MACE. The 3 yr MACE-free survival rate was 72.8 % in the positive exercise stress echocardiography group and 94.2 % in the negative group (p&lt;0.001). Multivariate Cox regression analysis showed that positive exercise stress echocardiography immediately post-stress, wall motion score index, N-terminal pro-B-type natriuretic peptide concentration, and age were independent risk factors for MACE (all p&lt;0.01).Conclusion    Exercise stress echocardiography demonstrated good diagnostic accuracy in patients with suspected CAD but without typical angina symptoms. It had significant predictive value for intermediate-term adverse cardiovascular events. Exercise stress echocardiography can be used for risk stratification and clinical decision-making in this population.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Стресс-эхокардиография</kwd><kwd>ишемическая болезнь сердца</kwd><kwd>атипичные симптомы</kwd><kwd>диагностика</kwd><kwd>прогноз</kwd><kwd>индекс оценки подвижности стенок</kwd><kwd>серьезные неблагоприятные сердечно-сосудистые события</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Exercise stress echocardiography</kwd><kwd>coronary artery disease</kwd><kwd>atypical symptoms</kwd><kwd>diagnosis</kwd><kwd>prognosis</kwd><kwd>wall motion score index</kwd><kwd>major adverse cardiovascular events</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Конфликт интересов не заявлен</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>No conflict of interest is reported.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Chong B, Jayabaskaran J, Jauhari SM, Chan SP, Goh R, Kueh MTW et al.
